Get Auxiliary heater Guide for Volkswagen California Van Third Generation (2015-2024)

Introduction

The auxiliary heater and ventilation system can be used to heat the vehicle interior in the winter and ventilate it in

the summer. It is able to clear ice, condensation and a thin layer of snow from the windscreen. The auxiliary heater

is supplied with fuel from the vehicle fuel tank and can be operated when the vehicle is stationary with the ignition

switched off. The auxiliary ventilation system is powered by the 12-volt vehicle battery.

Possible auxiliary heaters

Depending on the equipment in the vehicle, it may have an auxiliary coolant heater, auxiliary air heater or a

combination of both.

—The auxiliary coolant heater primarily heats the front end of the vehicle.

—The auxiliary air heater primarily heats the vehicle interior.

If your vehicle has a auxiliary coolant heater with remote control, the auxiliary heater can also be programmed via an

app on your mobile telephone . Information about the app, the requirements for use and availability, and about

compatible end devices is available on the internet .

Operating mode of the auxiliary heater

You will be able to select different modes depending on the type of auxiliary heater installed in the vehicle. If you are

unable to select a particular mode, the vehicle is not equipped with the relevant auxiliary heater.

—Vehicle interior and windscreen (auxiliary coolant heater).

—Vehicle interior (interior using auxiliary air heater).

—Ventilate (ventilate the vehicle interior). The vehicle interior is not cooled in ventilation mode.

Depending on the equipment in the vehicle, the temperature and the areas to be heated can be selected in some

modes.

Auxiliary heater exhaust system

The emissions generated by the auxiliary heater are removed via an exhaust pipe fitted underneath the vehicle. The

exhaust pipe must not be blocked by snow, mud or any objects.

DANGER

Among the emissions from the auxiliary heater is carbon monoxide, which is an odourless and colourless poisonous

gas. Carbon monoxide can cause people to lose consciousness. It can also cause death.

● Never switch on the auxiliary heater or leave the auxiliary heater running if the vehicle is located in enclosed or

unventilated spaces.

● Never program the auxiliary heater to switch on and run in unventilated or enclosed spaces.

WARNING

Parts of the auxiliary heater exhaust system become very hot. This can cause fires.

● Park the vehicle so that no part of the exhaust system can come into contact with any inflammable material

underneath the vehicle, e.g. dry grass.

NOTICE

Heat-sensitive food, medicine and other items could be either damaged or rendered useless.

● Never leave food, medicines or other temperature-sensitive objects in front of the vents.

ventilation).

— The yellow indicator lamp (fuel gauge) lights up .

— The charge level of the 12-volt vehicle battery is too low.

The auxiliary heater runs on for a short time after it is switched off manually or automatically so that the remaining

fuel in the system can be burnt off.

Operating noises can be heard when the auxiliary heater is switched

on.

If you park on a downhill slope with very little fuel in the tank(just above reserve level), the fuel gauge may be

inaccurate and lead to functional restrictions of the auxiliary heater.

outlet in front of the partition and one behind.

—Vehicles without partition: The air outlets are located on the B-pillar on the front passenger side. Depending on

the selected settings, the air from the vents can flow towards the front or the rear.

WARNING

175

People who are lightly or not at all sensitive to pain or extreme temperatures as a result of medication, disabilities or

chronic illnesses, e.g. diabetes, may suffer from burns if they get too close to the vents. These burns may take a very

long time to heal or may not fully heal at all. Please consult a doctor to determine your own level of health.

● People with a low sensitivity to pain or extreme temperatures should not sit in the areas around the vents.

NOTICE

Heat-sensitive food, medicine and other items could be either damaged or rendered useless.

● Never leave food, medicines or other temperature-sensitive objects in front of the vents.

NOTICE

Troubleshooting

The auxiliary heater is not switched on.

—The charge level of the 12-volt vehicle battery is too low.

The 12-volt vehicle battery will be discharged if the auxiliary heater runs several times for an extended period.

Drive the vehicle for an appropriate distance in order to recharge the 12-volt vehicle battery.

—There is only the reserve fuel quantity left in the fuel tank.

The interior temperature is slightly higher than expected

The temperature at which the auxiliary heater heats the vehicle interior could be slightly higher if the temperature

selector for the heating and fresh air system or manual air conditioning system was set to the highest setting before

the auxiliary heater was switched on. This also depends on the ambient temperature.

Water vapour under the vehicle

If the outside humidity is high and the outside temperature low, condensation may evaporate when the auxiliary

heater is running. If this is the case, steam may appear underneath the vehicle. The vehicle is not damaged.
